Chocolate swirl cookies

I've mentioned that I rarely bakes cookies or biscuits. We do tend to buy cookies / biscuits that have something to with chocolate. We ran out of bought snacks and since I have all the ingredients for this recipe, I quickly whip this up. I would be relying this as my go-to chocolate based cookies going forward. The quantity of sugar have been reduced to my taste which resulted in a more intense chocolate bite. For special occasions and a more decadent version, I intend to sandwich with chocolate butter cream!

**I halved this recipe and yield around 24 medium-size cookies
Ingredients  200g softened butter  300g soft brown sugar (in my halved recipe, I reduced from 150gm to 75gm) 2 tsp vanilla extract  2 eggs  300g self raising flour (used regular plain flour) 80g cocoa powder  1 tsp baking powder  300g choc chips (eliminated)

My additions
++ rum, to taste
++ pinch of salt,  if using unsalted butter

Method

1. preheat oven to 180 c/ gas 4
2. cream butter and sugar until light and fluffy, then beat in vanilla extract and eggs
3. in a separate bowl sift flour, cocoa and baking powder together
4. add flour mix to the creamed mix in stages( a third at a time) mix well. fold in choc chips until just combined.
5. spoon a tablespoon of the mixture on to a baking tray and just let it drop off the spoon, repeat until you have used up all the cookie mixture.
6. bake in preheated oven for 12 minutes, when you remove the cookies from the oven they will still be soft, leave to cool completely on the baking tray, where they will continue to cook slightly,when completely cold move to a cooling rack. then enjoy!
